Embodiment 1
[0018] Take 2500mL of P waste solution (GB / T6150.3-2009) in a 3000mL beaker, heat it on an electric furnace to concentrate the volume to about 800-1000mL, take it out and cool it slightly, and add liquid alkali to pH approx. 6. Add ammonia water to pH 8.5-9 to completely precipitate beryllium hydroxide, heat to boiling, filter with a Buchner funnel while hot, wash the precipitate with hot ammonia water-ammonium nitrate mixture for 10 times, and transfer the precipitate into a beaker. Add 8mL nitric acid to dissolve, dilute to 200mL after dissolving, then add ammonia water to pH 8.5~9, make beryllium hydroxide precipitate completely, heat to boiling, filter with Buchner funnel while hot, and use hot ammonia water-ammonium nitrate mixture Wash the precipitate 10 times, transfer the precipitate into a beaker, add 8mL nitric acid to dissolve, and dilute to 400mL after dissolution, which is used for the phosphorus removal step of the determination of tungsten trioxide in high-phosph...
Embodiment 2
[0023] Take 2500mL of P waste solution (GB / T4324.24-2012) in a 3000mL beaker, heat it on an electric furnace to concentrate the volume to about 800-1000mL, take it out and cool it slightly, add NaOH solution (500g / L) to pH about 6, add ammonia water to pH 8.5-9, make the precipitation of beryllium hydroxide complete, heat to boiling, filter with Buchner funnel while hot, wash the precipitate 10 times with hot ammonia water-ammonium sulfate mixed solution, put Move the precipitate into a beaker, add 6mL sulfuric acid to dissolve, dilute to 200mL after dissolving, then add ammonia water to pH8.5~9, make the beryllium hydroxide precipitate completely, heat to boiling, filter with Buchner funnel while hot, and use hot ammonia water -Wash the precipitate with ammonium sulfate mixture 10 times, transfer the precipitate into a beaker, add 6mL of sulfuric acid to dissolve, dilute to 400mL after dissolving, transfer to a 500mL separatory funnel, add 25mL of ammonium molybdate solution ...
